feat: accept Uint8Arrays as inputs for Vecs, add docs for bytecode inputs

[Dhaiwat10]

Summary

Before this PR, the VecCoder wasn't accepting input arrays of type Uint8Array. In some cases, like the compute_bytecode_root function from the bytecode Sway Lib, you need to pass in a Uint8Array to the Sway function.

I have tweaked the validation inside the VecCoder for the inputs, and also added some documentation around how to pass in bytecode to Sway functions.

You can pass in bytecode to any Sway function like so now:

import { arrayify } from 'fuels';

const { logs } = await contract.functions
  .compute_bytecode_root(arrayify(bytecodeFromFile))
  .call();

Closes #1950

This PR will unblock the Fuelnaut project, too.

Hmm IMO a Vec<u8> representing a byte array should actually be taking Bytes as the input? Which would then be picked up by the ByteCoder which accepts UInt8Array. Is this a sway built in function which accepts Vec<u8> when expecting bytes?

[Dhaiwat10]

@danielbate yes that is the case. All the functions in this Sway library (which is officially maintained and supported by us) accept bytecode as Vec<u8>

LGTM! One small nit.

Still looks great 😆
